Plumbing fixture

ABSTRACT

A plumbing fixture is disclosed which may include a wash basin positioned above a bodily waste. A transition compartment may be connected between the wash basin and the bodily waste basin for directing flow of fluid from the wash basin into the bodily waste basin.

BACKGROUND OF THE INVENTION

The present invention generally relates to a plumbing fixture, and more particularly, to a combination wash basin and bodily waste basin fixture.

Facilities such as public restrooms and homes may be scrutinized for space saving measures. Additionally, some public concerns may exist to find ways to recycle resources such as water.

In one exemplary scenario, the general public, in facilities such as an airport, may need to have many individual toilets and urinals as well as several wash basins. In some large scale airports, this may include several hundred separate wash basins, urinals, and toilets. Each wash basin, urinal and toilet may require its own respective water source for operation. The operation of a wash basin and a urinal or toilet separately may result in the use of many gallons of water per use.

On structure proposed by U.S. Pat. No. 6,119,285 includes a lavatory fixture including a urinal and a hand sink combined in a single lavatory unit. In this type of structure, the faucet appears to be within the same cavity as the urinal unit. A sensor detects when a user walks away from the fixture and releases a water flow to flush the urinal.

As can be seen, there is a need for a plumbing fixture that may recycle use of one fixture's water for use in a separate fixture's water.

SUMMARY OF THE INVENTION

In one aspect of the present invention, a plumbing fixture comprises a wash basin; a bodily waste basin; and a transition compartment connected between the wash basin and the bodily waste basin, wherein the wash basin is positioned above and external to the bodily waste basin.

In another aspect of the present invention, a plumbing fixture connectable to a wash basin comprises a bodily waste basin removably connected to the wash basin, wherein the bodily waste basin is connected to a drain of the wash basin and the bodily waste basin includes a first flow area; and a transition compartment connected to the bodily waste basin wherein the transition compartment is positioned below the drain and above the bodily waste basin wherein the transition compartment includes a second flow area smaller than the first flow area

These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Various inventive features are described below that can each be used independently of one another or in combination with other features.

Broadly, exemplary embodiments of the present invention generally provide a plumbing fixture combining a wash basin integrated with a bodily waste basin. Embodiments of the present invention may be beneficial for use in lavatories as a mechanism for using space efficiently. Embodiments of the present invention may also allow for recycled use of wash water originating from the wash basin for use in flushing bodily waste out of the bodily waste basin. Furthermore, exemplary embodiments may, in general, comprise an integrated structure or may comprise a bodily waste basin removably connectable to a wash basin.

Referring to FIGS. 1A-1C and 2, an exemplary embodiment of a plumbing fixture 10 may generally include a wash basin 20, a bodily waste basin 70, and a transition compartment 30. It will be understood that the plumbing fixture 10 may be attached to plumbing (not shown) of a lavatory (not shown).

The wash basin 20 may include an inner surface 25, a drain 28, and fixtures ports 15. It will be understood that wash basin fixtures BF may optionally be connected to the fixture ports 15. It will also be understood that the wash basin 20 may generally be concave shaped and the inner surface 25 may slope downward toward the drain 28. Transition side surfaces 51 may be positioned near a bottom periphery 23 below the drain 28 defining a gradual constriction of a flow area 67. The flow area 67 may be defined by a passage 69 spanning between the two side surfaces 51. The drain 28 may be a free flowing drain or may be a controlled flow drain where fluid may be held in the wash basin 20 until a desired fluid capacity for release is achieved.

The bodily waste basin 70 may include a generally sloped inner surface 75 configured to receive bodily waste (not shown) and move the bodily waste down toward an outlet 80. An upper periphery 73 of the bodily waste basin 70 may include side inner surfaces 71 defining a passage 63 permitting flow of fluid from the transition compartment 30 onto the inner surface 75. A bodily waste basin flow area 65 may be defined by a gradual expansion of the passage 63 spanning between the inner surfaces 71. The bodily waste basin may in one exemplary embodiment, be a urinal. In another exemplary embodiment, the bodily waste basin 70 may be a toilet.

The transition compartment 30 may be positioned between the wash basin 20 and the bodily waste basin 70. The transition compartment 30 may be connected to the bottom periphery 23 of the wash basin 20 and the upper periphery 73 of the bodily waste basin 70. The transition compartment 30 may include a water deflector 45 positioned underneath the drain 28. It will be understood that the water deflector 45 may be a separable element or may be molded into the transition compartment 30. It will also be understood that the water deflector 45 may be hollow or solid. The water deflector 45 may include a generally rounded deflection surface 40. The deflection surface 40 may also include a deflection edge surface 44 extending along the sides of the water deflector 45. The transition compartment 30 may be lengthened for increased water flow velocity due to gravity, however, for ease of illustration, the transition compartment 30 is shown relatively compact in relation to the wash basin 20 and bodily waste basin 70.

The transition compartment 30 may include an outer side surface 53 defining a generally hourglass shape between the wash basin 20 and the bodily waste basin 70. The outer side surface 53 may cooperate with the inner side walls 35, inner front wall 37, inner rear wall 39 and the water deflector 45 to define fluid choke areas 55. Transition compartment fluid flow areas 60 may be defined by passages 66 spanning between the inner side walls 35 and the water deflector 45. In one exemplary embodiment, the water deflector 45 may be attached to the inner front wall 37 leaving the sides and rear of the water deflector disconnected for passage of fluid between the inner side walls 35 and the inner rear wall 39. Thus, the passages 66 may comprise a circular arc passage circumventing the water deflector 45 along its sides and rear deflecting fluid flow against the side inner surfaces 35 and inner rear wall 39. It will be understood however, that other attachments of the water deflector 45 to the transition compartment 30 may be contemplated such as bridging sides of the water deflector 45 to the inner side walls 35 or by suspending the water deflector 45 from the drain 28 while achieving similar fluid flow.

In operation, a user (not shown) may use the bodily waste basin 70 for disposal of bodily wastes. When the user is done with using the bodily waste basin 70, the user may operate fixtures BF on the wash basin 20 to wash the user's hands with fluid. In one exemplary use, the fluid may be water originating from the fixtures BF. As the water flows down the inner surface 25, it may build up momentum due to gravity as the water flows toward the drain 28. As the water is released through the drain 28, it begins to encounter lower pressure as it crosses through the flow area 67 and transitions into the transition compartment 30 commencing a build-up of velocity. If desired, the water may be temporarily detained in the wash basin 20 to build up a sufficient volume of water by control of the drain 28. Upon release, the detained volume of water may flush down through plumbing fixture 10.

As water flows into the transition compartment 30, it may encounter the water deflector 45 by making contact with the deflection surface 40. Water encountering the water deflector 45 may flow around the deflection surface 40 and onto the deflection edge surface 44 into the fluid choke area 55 and the passages 66 without flowing outward toward the user thus, assisting in mitigating the occurrence of splashing on the user. The deflection edge surface 44 may cooperate with the inner side walls 35 and inner rear wall 39 to create a venturi effect on the water flow through the passage 66. The velocity of water may increase as it flows through the flow area 60 which may be smaller in area and thus, lower in pressure relative to the both the flow area 67 and the flow area 65. As the flow of water passes through the flow area 65 of the bodily waste basin 70, a higher pressure may result from the water flow exiting the constricted transition compartment 30 and entering the bodily waste basin 70. The increase of pressure may assist in the water flow traveling along the inner surface 75 and flushing any bodily waste out of the bodily waste basin 70.

Referring to FIG. 3, another exemplary embodiment of a plumbing fixture 100 is shown. Plumbing fixture 100 is similar to plumbing fixture 10 except that the wash basin 20 and the bodily waste basin 70 may be disconnected and separate elements that may be connectable to one another. The transition compartment 30 may be connected to either the wash basin 20 or the bodily waste basin 70. In one exemplary embodiment illustrated, the transition compartment 30 is depicted as being part of the bodily waste basin 70 connected to the bodily waste basin 70 at an upper periphery. The water deflector 45 may be suspended from the drain 28 via suspender 151 as illustrated and inserted into the transition compartment 30 during connection of the wash basin 20 and the bodily waste basin 70, or the water deflector 45 may be affixed to an anterior portion of the transition compartment 30 as illustrated previously in FIG. 1B and FIG. 2. A connector 150 may be employed to connect the wash basin 20 to the bodily waste basin 70. The connector 150 may be, in exemplary embodiments, a threaded connection or may be an interference fit. In one exemplary embodiment, a wash basin 20 may be a fixture previously installed in a lavatory and may thus, be adapted by installing the bodily waste basin 70 underneath the wash basin 20. It will be understood that sealing elements such as gaskets or silicone may be applied around the connector 150 providing a water tight seal.
